The important application for the infrared photodetectors is mainly thermal imaging by focal plane arrays (FPAs) for military and commercial purposes. So far, most mid-wavelength infrared (MWIR) and long-wavelength infrared (LWIR) FPAs are based either on HgCdTe (MCT) or quantum well infrared photodetectors (QWIPs). Even though those technologies are well...
An efficient unified incremental high-level and physical-level synthesis algorithm was presented in Chapter 2, which enable the tight integration between high-level and physical-level design. Chapter 3 presented a temperature-aware high-level synthesis algorithm built upon the framework of Chapter 2. Temperature variations and hot spots account for reliability issue and require...
I/O performance has perpetually lagged well behind that of processors. This gap is made even more pronounced in the field of high-performance computing. While simply adding more network bandwidth and increasing the number of storage units is a simple way to increase theoretical peak I/O bandwidth, the software libraries for...
With aggressive scaling down of feature sizes in VLSI fabrication, process variations, crosstalk and buffering have become critical issues to achieve timing closure in VLSI designs. Timing analysis and optimization techniques need to consider each of them and also their interactions. There are many statistical timing analysis researches to handle...
Video transmission over wireless networks to multiple mobile users has remained a challenging problem due to potential limitations on bandwidth and the time-varying nature of wireless channels.

FPGAs are evolving at a rapid pace with improved performance and logic density. However, power efficiency of FPGAs has continuously lagged behind, and hence power optimization of FPGAs is crucial. Trends in technology scaling makes leakage power a serious concern for designers; on the other hand, routing power is the...
The emergence of lightwave communication and computing, and applications in nanophotonics require an understanding of complex electromagnetic wave phenomena in linear and nonlinear materials having frequency-dependent and intensity-dependent polarizations. Both the complexity of the underlying physics and the problems required for modern engineering applications necessitate understanding the vector-nature of the...
New telecommunication techniques utilizing distinctive quantum properties, e.g., measurement uncertainties and entanglement, extend the capabilities of existing systems. Quantum cryptography, as an example, provides physical layer security enforced by fundamental physical laws, while modern cryptographic techniques rely on assumptions of intractability of certain mathematical problems with limited computational power.
